Sub Door Question, Redoing the Premium Audio package Options

[jbcustom]

So I decided to finally go full aftermarket with the speakers in my celica. problem is that I have the premium audio package. I have a total of 8 speakers in my car.
These include:
8" paper woofers in the door
4"midrange components in the door
3/4" tweeters in the door
6x9 in the rear.

I have already purchased a Pioneer 8600MP for the HU. And pioneer's 3 way 6x9 and 4" speaker. Would any one have any recommendations on subs that will fit the door? I want sound thats loud and crisp. I was going to go with Polk Momo 8" subs. Any further suggestions?

I am going to make sure to get pictures of the project. I plan on moving the battery to the back. I have to do all custom wiring because of a funky "not standard" premium amp (the wiring harness for the 89+ toyotas doesnt match). Any comments would be more than helpful.

If you want to go with an 8 inch sub ( and not an 8 inch woofer, which I think is what the factory is ), I would definitely recommend an aftermarket amp.

How about this scenario: a 4 ch amp to power the subs and 6x9s, and your head unit to power the 4s and the tweets?

As far as the depth question, our doors DO have a decent amount of depth. The problem is that if you want to use the factory mount for the speaker, you don't have much room for any size magnet on the speaker. In other words, the hole where the magnet would poke through is not very big. If you're willing to create your own speaker mount and maybe do a little cutting into the door - then YES, there's room.

One last note on the subs: If you are buying TRUE subs, and not just woofers, then make sure you get something that is designed for infinite baffle and NOT for an enclosure. Unfortunately, most subs are designed for enclosures of some sort. If you don't, you probably won't be happy with the results.
